INDIANAPOLIS -- As Justin Fields took the first snap from rookie center Zach Frazier on Sunday, the Pittsburgh Steelers quarterback stumbled, tripping over Frazier's feet and falling to the turf.
He quickly flipped the ball to running back Najee Harris, but the Indianapolis Colts defense swallowed him up and the play went for a loss of 3 yards.
The rest of the first half didn't go much better for the Steelers offense in the 27-24 loss, their first of the season. Other lowlights included a failed fourth-down conversion on the second drive and a George Pickens fumble near the goal line in the second quarter that wiped away the team's most promising drive of the half.
